Was she fat from the start? Then yes. Did she gain a few pounds but is overall a great wife? Then yes. Did she put on a ton of weight and is a mediocre wife? Then not so much. Did she put on a ton and is a horrible wife? Then, not at all!
if you are asking this question than i guess not cuz if you love her than that stuff wouldnt matter so i say cut ur losses and go find a better lookin chick that works as a house cleaner so all your basses are covered and please her
